Power failure stop function (Pr. 261 = "1, 11, 21")
Even if power is restored during deceleration triggered by a power failure, deceleration stop is con-
tinued after which the inverter stays stopped. To restart operation, turn the start signal OFF then ON
If the automatic restart after instantaneous power failure is selected (Pr. 57 "Restart coasting time"
≠ "9999") while the power failure time deceleration-to-stop function is set enabled (Pr. 261 = "1,
11, or 21"), the power failure time deceleration-to-stop function is disabled.
When the power failure time deceleration-to-stop function is enabled (Pr. 261 = "1, 11, 21"), the
inverter will not start even if the power is turned ON or inverter reset is performed with the start
signal (STR/STF) ON. Turn OFF the start signal once and then ON again to make a start.
